Remove LCK Virus (.[triplock@tutanota.com].LCK Files Ransomware) – Dharma Ransomware

LCK – Ransomware

The LCK stands for a ransomware-type infection. The infection comes from the Dharma ransomware family. LCK was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are unable to use them. LCK adds the “.[triplock@tutanota.com].LCK” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by LCK, will be renamed into “myphoto.jpg.[triplock@tutanota.com].LCK“. As quickly as the encryption is finished, LCK places a special text file into every folder containing the encrypted data.

The message given by LCK text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives belonging to the Dharma type. It actually mentions that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by LCK is still not properly examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is completely distinct. It is impossible to restore the files without the key available.

Another technique of LCK is that the victims cannot get to the key. The key is kept on a particular server run by the frauds connected with LCK ransomware. To get the key and recover the important info people need to pay the ransom.

However, regardless of the asked for amount, people need to stay away from paying the ransom. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people simply lose their money for absolutely nothing.

We highly recommend that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack LCK ransomware and to recover the information data for free. Hence, the only right decision is to recover the lost data from the available backup.
